853480 divided by 45 
Let's see how many times 45 fits into 853480.

Let's proceed to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 45

Going ahead to step 2:
85 divided by 45 is 1 with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 45 from 85, we get 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 45

Step 3:
45 goes into 403 8 times with a remainder of 43.
The next digit of our result is 8. 
Result so far: 18.0
If we take 360 away from 403, we end up with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 45

Step 4:
When dividing 434 by 45, we get 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 189.0
Subtracting 405 from 434 leaves us with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 45

Advancing to step 5:
The number 45 fits into 298 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 1896.0
If we subtract 270 from 298, we get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 45

Step 6:
45 can be fit into 280 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 18966.0
If we subtract 270 from 280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 45, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 18966.2
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
45 can be fit into 100 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 18966.22
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 18966.22 with a remaining 0.01.
